What is the current energy density of lithium iron phosphate batteries?

At present, China's automotive power battery technology route is chosen to be the same as the lithium iron phosphate route in the United States. Undoubtedly, lithium iron phosphate batteries have many advantages: high stability and relatively cheap price, but their energy density (higher energy density to better solve the mileage problem) has very limited room for improvement. It is understood that the energy density of individual lithium iron phosphate batteries can reach 157Wh/kg, but after grouping, the energy density of individual batteries decreases to 100Wh/kg.

The current capacity density of lithium iron phosphate batteries is generally around 150Wh/kg, and even if done better, it is still around 160Wh/kg, which is significantly different from the 200Wh/kg energy density of ternary batteries. The upcoming 32131 high-energy density cylindrical lithium iron phosphate battery has a single energy density of 180Wh/kg, and passenger cars using this battery can achieve a range of over 300km. With the development and application of various new materials and technologies, Guoxuan High tech plans to increase the maximum capacity of lithium iron phosphate single cell to 200Wh/kg in 2019.

Guoxuan High tech revealed to investors on the interactive platform that this year, BAIC New Energy's EC180 and EC220 models will use the company's high-energy density lithium iron phosphate batteries. At present, the energy density of the company's high-energy lithium iron phosphate battery is close to the level of ternary 333, and it is significantly better than ternary batteries in terms of cycle life and cost control. It is very suitable for large-scale use in mid to low-end vehicle models, and the energy density and performance of the product are constantly improving.
